To all whom it may concern: i

Be it known that 1, JAMES Ewmes SAN- 1 DEBS, a citizen of the United States, residing at Dalton, in the county of Whitfield and i State of Georgia, have invented a new and useful Pea Hulling and Separating Machine, of which the following is a specification.

This invention relates to machines for threshing or hulling and separating various seeds and grainssuch as peas, beans, sorghum and the likeand among the objects of the invention are to improve and simplify the construction and operation of this class of devices.

Vith these and other ends in view, which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which 5 will be hereinafter fully described and particularly point ed out in the claim.

In the accompanying drawings has been 1 illustrated a simple and preferred form of the machine, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations, and modifications within the scope of the invention may be made when desired.

In the drawings, Figure 1 is a side view of a machine constructed in accordance with the principles of the invention. Fig. 2 is a rear elevation of the same. Fig. 3 is a vertical sectional detail view taken through the hull ing mechanism. Fig. i is a detail side view of the casing of the hulling mechanism. Figs. 5 and 6 are detail views illustrating a modification.

Corresponding parts in the several figures are indicated throughout by similar characters of reference.

Upon a suitably-constructed frame A is supported a cylindrical casing, which may be described as consisting of a back member 2, a lid 3, and a wall 1, which latter is preferably constructed of sheet metal, while the back and the lid may be constructed either of wood or of metal. Axially through the cas ing 1 extends a shaft 5, for which suitable bearings are provided upon the frame of the machine, and said shaft carries within the casing a disk 6, said disk and the back of the casing being provided upon their opposing faces with teeth or spikes 7, which are disposed in circular relation and intercurrently ient manner.

upon the disk and the casing, so that when the disk is rotated with the shaft 5 the teeth upon said disk will pass between the teeth i upon the back of the casing without interfering or contacting therewith. When the 1 disk and the back of the casing are constructed of wood, these teeth or spikes may be driven into the wood, as will be readily understood; but within thescope of the invention the disk as well as the back of the casing may be constructed of cast metal, in which event the teeth will be formed integrally therewith, as will be readily understood by reference to Figs. 5 and 6 of the drawings. When the teeth are thus formed, it is preferred that the bases of said teeth be thickened or reinforced, as shown in Figs. 5 and 6, where 6 designates a portion of the disk, 7 the teeth, and 8 the thickened or reinforced bases of the teeth.

It is also to be considered within the scope of the invention to construct the back of the casing, as well as the disk, of other than cast metal, in which event the teeth may be mounted or secured in any suitable conven- The back of the casing and the disk may also be constructed of cast metal and the teeth of wrought iron or steel, suitably bolted or otherwise secured upon the back and disk.

The back of the casing is formed with a centrally-disposed boss or collar 9, through which the shaft 5 extends, and which serves to keep the disk 6 properly spaced from the back of the casing.

The shaft 5 is provided near its rear end with a pinion 10, meshing with a spur-wheel 11 upon a shaft 12, which is supported for rotation in suitable boxes or bearings upon the frame A. The spur-wheel 11 is provided with a crank 13, whereby it may be rotated for the purpose of driving the shaft 5.

The back 2 of the huller-casing is provided with a feed-opening 14:, with which is detachably connected a feed spout or hopper 15. Said spout or hopper may be secured in position detachably by any suitable means, and it has been shown as provided with a feedtable 16, hingedly connected therewith and supported upon a post or upright 17. This arrangement, however, may be changed or modified within the scope of the invention. The hinged feed-table may be dispensed with when desired.

The huller-casing is provided at its lower edge with an obliquely or tangentially eX- tending spout 18, through which the threshed material will be discharged into an inclined chute 19, having a detachable bottom board 20, which supports an extension 21 of said chute. The bottom board 20 when in operative position, as best seen in Fig. 3, is supported by means of cleats 22. The lower end of the chute 19 has a lateral dischargeopening 23, underneath which is supported a shaking shoe, consisting of a box 24, having a sieve-bottom 25 and an inclined dischargechute 26 below said sieve-bottom, one end of said box being open for the discharge of waste material. One end of said shoe is supported adjustably by means of a pail 27, and the other end is supported by an arm 28, extending from arock-shaft 29, which is provided with a crank 30, connected, by means of a pitman 31, with a wrist-pin 32 upon the face of the pinion 10 at the rear end of the shaft 5. Thus when said shaft is rotated a shaking or vlilbratory movement will be imparted to the s cc.

Supported in the frame A, adjacent to the wind chute 19, is a fan-casing 33, the discharge of which is directed through the spout 34 into the wind-chute beneath the dischargespout 18 of the huller-casing. Supported for rotation in the fan-casing 1s a fan-carrying shaft 35, having a sheave or pulley 36, which is connected by a belt 37 with a larger sheave or pulley 38 upon the shaft 5, whereby the fan will be driven.

The operation of this invention will be readily understood. The material that is to be threshed is fed through the hopper and into the huller-casing, where it passes between the back of the casing and the revolving tooth-carrying disk, the said material being thoroughly threshed and comminuted by the action of the teeth upon the revolving disk and upon the back of the casing. The threshed material is discharged through the spout 18 into the wind-chute and is there subj ected to the action of the blast from the fan, whereby the chaff, hulls, and all light material will be blown out through the windchute, while the seed will gravitate through the lateral discharge-opening into the shaking-shoe, where it will pass through the sieve and be dischargedover the inclined dischargechute 26 into a box or suitable receptacle, which may be placed underneath, while the tough unmatured bits of pods or other material which may gravitate along With the seed intothe shaking-shoe will be discharged over the open end of the latter, said shakingshoe being supported at a suitable inclination which will prevent the discharge of seeds over its open end along with the waste material.

By the construction herein shown and described a very simple, inexpensive, and thoroughly efficient machine is produced for the purpose of threshing and separating such products as peas, beans, and the like.

The machine is light and compact, and it may be conveniently packed into small compass for storage or shipment, the projecting parts, such as the hopper and the Wind-chute being connected detachably with the casing, so that when the machine is to be shipped or stored the said parts may find accommodation within the frame.

The general construction is simple, and the machine is therefore not liable to get out of order, and it may be successfully operated and maintained in good working condition without the use of skilled labor.

Having thus described the invention, what is claimed is A hulling-machine consisting of a cylindrical huller-casing provided at its lower edge with a tangently-extending dischargespout, the back wall of the said huller-casing being providedwith teeth, a hopper adapted to be attached to said casing adjacent to a feedopening in the back wall of the latter, an inclined wind-chute supported adjacent to and receiving the material discharged through the discharge-spout of the huller-casing, a fan-casing connected with the wind-chute adjacent to the discharge-spout of the hullercasing, said huller-casing being vertically arranged with relation to the hopper, a disk rotatably supported Within the huller-casing and having teeth extending in the direction of the back of the casing and disposed intercurrently with the teeth upon the back of the casing, all of said teeth being provided with straight edges located at right angles to the teeth-supports, the material constituting the teeth being thickened toward the base at the opposite side of said straight edges, the said straight edges being adapted to engage the material passing through said huller-casing.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.
